Did they date the wood from the ship or its cargo?
The ship could have been 50 years old when it sank........................
Hard to say. Regarding the Uluburun wreck (the earlier topic), a piece of plain lumber from the cargo could be spared and was RC dated. It was at first trumpeted as being confirmation of the age. Later it was realized that the newest ring was centuries too young for the conventional dating of the wreck. The explanation [sic] was that centuries later, this piece of wood drifted along, then sank and embedded itself in the wreck. Wood floats until its convenient for it to arbitrarily sink. :^)
Ah, it sez from the ship itself and its final cargo.
